如何将文本输入Facebook';使用WWW::Mechanize::Firefox的事件表单?

my @selectors = $mech->selector('input');
foreach my $selector (@selectors) {
$mech->field( $selector, 'hello world');
}
# attempts to publish event, results in form errors because fields are blank
$mech->click({ synchronize => 0, xpath => '//button[text() = "Publish"]' });
# test to see if values are getting set.
# this returns 'hello world' as so values are getting set
say $mech->value($selectors[2]);
# test to see if an input field can be selected with an xpath
# this works
$mech->click({ synchronize => 0, xpath => '//input[@placeholder="Include a place or address"]' });
Facebook生成的表单不便于在文本字段中输入数据。这些字段没有name属性,并且不能用css选择器区分(尽管可以用xpath选择),如最后一行所示
由于无法在字段中输入文本,Facebook会抛出错误,因为它认为字段为空,即使我使用$mech->field
成功地将值输入字段
有没有办法将文本输入Facebook的表单以添加事件
更新
我在这方面取得了一些进展。我至少能够使用以下代码填写一些字段(事件名称
和位置
):
my $field = $mech->xpath( '//input[@placeholder="Include a place or address"]', one => 1);
$field->{value} = 'Room 315, City Hall';
$field = $mech->xpath( '//input[@placeholder="Add a short, clear name"]', one => 1);
$field->__click;
$field->{value} = "License committee meeting";
$mech->click({ synchronize => 0, xpath => '//button[text() = "Publish"]' }, 10, 10);
不幸的是,当我用以下代码单击“发布”按钮时:
my $field = $mech->xpath( '//input[@placeholder="Include a place or address"]', one => 1);
$field->{value} = 'Room 315, City Hall';
$field = $mech->xpath( '//input[@placeholder="Add a short, clear name"]', one => 1);
$field->__click;
$field->{value} = "License committee meeting";
$mech->click({ synchronize => 0, xpath => '//button[text() = "Publish"]' }, 10, 10);
将清除
事件名称
和位置
文本字段,就像未输入任何内容一样。不确定此时还可以尝试什么。没有API是有原因的。尝试自动化只会一次又一次地中断。
